Security Decision Documentation¶

Category: Legal-Technical Analysis

Purpose¶

Records a significant security-related decision: what was decided, why, who was involved, and what evidence or inputs were used. Supports accountability and audit.

Audience¶

Internal (leadership, audit, future decision-makers) and potentially external (regulators, counsel). Formal record.

Typical structure¶

• Decision — Clear statement of what was decided.
• Date and participants — When and who (individuals or roles).
• Context — What triggered the decision (incident, finding, project).
• Options — Alternatives considered.
• Rationale — Why this option; key factors (risk, cost, compliance).
• Evidence or inputs — Documents, assessments, or advice relied on.
• Commitments — Follow-up actions, review dates, or conditions.
• Approval — Sign-off or acknowledgment.

When to use¶

• Major control or architecture decisions.
• Risk acceptance or exception approval.
• Post-incident or post-audit decisions that may be scrutinized later.

Evidence linkage¶

Decision record should reference supporting artifacts (risk assessment, architecture doc, legal advice). Becomes evidence of informed, documented decision-making.
